Download speed much lower that Upload speed with Deco XE75 Pro Mesh
Recently purchased 2 Pack XE75 PRO and getting some weird (and very disappointing) results with download speeds being markedly lower than upload speeds.
My Set up:
ISP : Voneus Fibre 1000/1000 using Zyxel Router
Main Deco XE75 PRO connected over Ethernet, using Cat 6 cable, to Zyxel Router and in Access Point Mode
Second Deco XE75 PRO situated right next to Main Deco XE75 PRO
Ran network optimisation on Deco's and no issues or interference reported
For Wifi tests Laptop was within 5 feet of Decos
Test Results:
Using Ookla Speedtest to "razorblue" site Manchester UK
All results averaged over 10 tests
OK Tests ....
- Laptop via Ethernet connection directly to Zyxel Router : 920 Mbps Download / 940 Mbps Upload
- Laptop via Ethernet connection to Main Deco XE75 Pro : 930 Mbps Download / 931 Mbps Upload
Where it starts to go wrong ....
- Laptop via Ethernet connection to Second Deco XE75 Pro : 359 Mbps Download / 935 Mbps Upload
- Laptop via Wifi 6 (not 6E) connection to Main Deco XE75 Pro : 299 Mbps Download / 559 Mbps Upload
- Laptop via Wifi 6 (not 6E) connection to Second Deco XE75 Pro : 272 Mbps Download / 601 Mbps Upload
It seems that the Wifi Backhaul connection between the Deco's is not performing well (even though they were right next to each other)
Wifi 6 connections should be providing a much better speed than tha Deco's are showing, i've ordered a 6E card for the laptop and will check these tests again.
Help Needed:
What could be causing the marked difference in download speeds when compared to upload speeds?
What could be causing the difference in speed differences between wired and wifi connections to the Decos?
What can I do to improve / fix these issues?
Please help .... can't help feeling i've invested a lot of money into dodgy tech.
